HW-070 PWM DC motor speed controller 5V-16V 12V speed switch 10A switch function LED dimming speed module Maximum voltage: 16V Minimum voltage: 5V Continuous current: 10A Maximum short-time current: 20A for less than 10 seconds Speed control mode: PWM stepless speed regulation, can also be used for light adjustment Control mode: speed control potentiometer (clockwise click to open, continue rotating clockwise to increase speed from 1% to 99%) Duty cycle: 0% to 99% (0% position is the leftmost position of the potentiometer when the switch is off) Current consumption when idle: 0.002A Efficiency: up to 98% Dimensions: 3cm long (excluding potentiometer), 2cm wide, 1.4cm This module supports customization based on customer requirements, including modifications to board shape, mounting method, current and voltage parameters, and addition of other functions.The device is primarily designed for motor speed control.When used for LED dimming, the LED can operate safely when connected directly to the power supply.The dimming range adjusts from full brightness to completely off.If the LED would be damaged when connected directly to the power supply without a resistor, a current-limiting resistor must be used in series to prevent damage to the module.Compatibility Disclaimer: This is an aftermarket replacement part.Any brand names or model designations mentioned are used solely for the purpose of demonstrating compatibility.
